API Ledger for DSH

English · 简体中文 · 中文完整文档

See what this conversation costs, without leaving it.

API Ledger brings token usage and estimated API spend into DeepSeek Harness: a full conversation report, a settings dashboard, a compact composer total, and a one-line daily total in the sidebar.

Illustrated feature overview with sample data, not a screenshot of a live account.

English

Why use it?

If your workflow involves switching between API routes or opening a separate report to check costs, these are the features to look at:

• Costs where you work. Session spend below the composer; today's spend in the sidebar. Click the daily total to open the full settings report.
• Same model, different prices. Pricing is keyed by route and model. An official endpoint and a gateway can have different rates without contaminating each other's estimates.
• Group deliberately. Routes remain separate by default. Give them the same billing group to combine their reports; a shared key reference never silently combines accounts or implies shared balance.
• Two currencies, one consistent view. CNY/USD display selection is remembered and shared across all four views.
• Make estimates explainable. Recent calls show their pricing source. Unknown prices stay unpriced rather than looking free, and historical records retain the rates originally used.
• No separate dashboard service. Usage capture and preferences live locally in the plugin. It does not read API key values or upload ledger data to a plugin-owned service.

These are concrete workflow benefits, not a claim that other usage plugins lack them. This plugin measures recorded usage and estimates cost; it does not retrieve provider invoices or account balances.

Four views

View	What it answers
Conversation → API Ledger	What has this conversation cost? Recent calls, model costs, token composition and usage trends.
Settings → API Ledger	Where does spending go across conversations? Date ranges, today/yesterday comparison and pricing preferences.
Below the composer	How much has this session used so far?
Sidebar footer	How much have I used today? One line, with a click through to settings.

Install

Requires Node.js 20+ and a compatible DSH installation. Tested with DSH Desktop 2.0.13 / bundled DSH 0.1.5-rc.2. No build step or runtime npm dependencies.

DSH Desktop — GitHub installation

git clone https://github.com/LAwLi3tCoding/dsh-api-ledger.git
cd dsh-api-ledger
node scripts/install.mjs

Restart DSH Desktop. Open Settings → API Ledger, or the API Ledger tab in a conversation. Keep the cloned folder: installation links to it. Update with git pull, then restart. Uninstall this linked installation with node scripts/install.mjs --uninstall.

DSH CLI — a CLI-managed profile

# From GitHub
dsh plugin --profile web add github:LAwLi3tCoding/dsh-api-ledger

# From npm
dsh plugin --profile web add dsh-api-ledger

Replace web with your CLI-managed profile. DSH 0.1.5-rc.2 reserves desktop for Electron, so dsh plugin --profile desktop add ... is rejected. Use the desktop installation above or the desktop marketplace once the listing is merged; marketplace submission is not the same as availability.

Configure pricing

Open Settings → API Ledger → Accounts and pricing. Select a route and model; save before switching models.

Mode	Behavior
Official tariff estimate	Default for recognized DeepSeek official endpoints without an explicit override. Applies the bundled USD tariff and peak/off-peak rules.
Reference estimate	Explicit opt-in to a fixed DeepSeek off-peak USD snapshot. Does not adjust for time or holidays.
Custom price estimate	Set currency and prices per million tokens: uncached input, output, cache read and cache write. Zero is valid.
Usage only	Record tokens without inventing a cost. Default for other endpoints.

Official endpoint detection checks the effective URL, including the DeepSeek adapter's launch-environment override. A route's name alone never establishes official pricing. The bundled official price snapshot was verified on 2026-09-21. It supports deepseek-flash, deepseek-v4-flash, deepseek-v4-flash-vision-exp and deepseek-v4-pro. Peak selection uses request start time and the 2026 Chinese holiday calendar. Unsupported models or calendar years remain unpriced. Prices update with plugin releases, not through a live pricing API.

Names and groups affect the current report presentation. Price edits affect future calls only. Existing custom preferences survive upgrades. Reset/delete removes ledger preferences for that route, not DSH model settings or historical calls. Inactive routes are grouped separately; preference-only routes disappear when removed.

Accuracy and data boundaries

• CNY/USD is display conversion, using fixed 1 CNY = 0.14 USD; it is not a live exchange rate or a provider's currency settlement rate.
• A call is recorded when it ends and supplies usage. Views refresh every 10 seconds while visible; today follows the client calendar.
• Costs are estimates, not invoices, remaining balances, budgets or subscription charges. Partially priced totals include only known costs.
• Historical calls keep original amounts and rates. A warning flags legacy USD numbers possibly labelled as CNY; it does not rewrite them.
• Uncached input and cache tokens are separate buckets. Reasoning tokens are not charged a second time. Adapters must report compatible normalized usage.
• Calls before installation are not imported. Missing usage cannot be reconstructed; the running process shows a missing-usage count. Nested wrappers are deduplicated, but an outer call that fans out to multiple upstream streams can still undercount.
• Preferences are stored in $DSH_HOME/api-ledger/config.json; records in records.jsonl, with rollup.json as a derived summary. Without DSH_HOME, use ~/.dsh/api-ledger/. These local files and credentials are not part of the package. In-memory history is capped at the latest 200,000 records.

Development

npm run check
npm test
npm pack --dry-run

Tests exercise pricing boundaries, endpoint recognition, immutable historical amounts, configuration conflicts, same-origin writes, stream capture, report periods, bilingual UI and the four display slots.

简体中文

不用离开会话，就能查看本次对话花了多少钱。

API 账本把 Token 用量和 API 估算费用放进 DSH：会话完整报告、设置页总览、输入框下方的会话金额，以及左下角的一行今日金额。

哪些地方用起来方便？

• 随手查看费用：不用频繁打开独立报表；会话费用放在输入框下面，今日费用放在侧边栏，点击即可打开设置中的账本。
• 相同模型可以按不同接口计价：价格按「路由 + 模型」配置，官方接口和企业网关互不混用。
• 分组由使用者决定：默认按路由分别统计，需要时再设置相同账单分组。不会因为共用凭据引用就自动合并，也不会把展示分组当作共用余额。
• 四处展示同步切换币种：CNY/USD 选择会保存并同步，避免不同页面各用一种显示币种。
• 能看懂费用怎么来的：最近调用标明计价来源，未配置单价显示未计价，历史记录保留当时使用的单价。
• 无需部署额外服务：用量与配置保存在本机，不读取 API Key 的值，也不上传到插件自建的统计服务。

这些是插件的具体使用价值，不代表其他用量插件都不具备相同能力。这里统计的是已记录用量与估算费用，不是供应商账单或账户余额。

四处展示

位置	用途
会话 → API 账本	本会话费用、最近调用、模型分布、Token 构成和用量趋势
设置 → API 账本	跨会话报表、周期筛选、今日／昨日对比、账户与计价
会话输入框下方	本会话已用金额
侧边栏左下角	单行今日费用，点击打开账本设置

安装

需要 Node.js 20+ 和兼容的 DSH。已在 DSH Desktop 2.0.13／内置 DSH 0.1.5-rc.2 验证；插件无需构建，没有运行时 npm 依赖。

DSH Desktop：从 GitHub 安装

git clone https://github.com/LAwLi3tCoding/dsh-api-ledger.git
cd dsh-api-ledger
node scripts/install.mjs

重启 DSH 后，打开「设置 → API 账本」或会话的「API 账本」Tab。安装使用本地链接，请保留克隆目录。更新时执行 git pull 后重启；卸载该链接安装时执行 node scripts/install.mjs --uninstall。

DSH CLI：安装到 CLI 管理的 profile

# GitHub 安装
dsh plugin --profile web add github:LAwLi3tCoding/dsh-api-ledger

# npm 安装
dsh plugin --profile web add dsh-api-ledger

将 web 换成自己的 CLI profile。DSH 0.1.5-rc.2 的 desktop profile 由 Electron 专管，不能直接使用 dsh plugin --profile desktop add ...。桌面端请使用上面的安装脚本，或在市场收录完成后通过桌面市场安装；提交 PR 不等于已经上架。

配置计价

打开「设置 → API 账本 → 账户与计价」，选择路由和模型。每个模型单独保存，切换前先保存当前修改。

方式	含义
官方价表估算	已识别的 DeepSeek 官方直连在没有显式配置时默认使用，按内置 USD 价表及峰谷规则估算
参考价估算	手动选择固定的官方非高峰 USD 快照，不判断时间和节假日
自定义单价	按每百万 Token 填写非缓存输入、输出、缓存读和缓存写价格及币种；允许零价格
仅记录用量	不猜测费用；其他接口的默认方式

官方接口按实际 URL 识别，并考虑 DeepSeek 适配器的启动环境覆盖；名称包含 DeepSeek 不代表官方直连。内置官方价表核验日期为 2026-09-21，支持 deepseek-flash、deepseek-v4-flash、deepseek-v4-flash-vision-exp 和 deepseek-v4-pro。按请求开始时间及 2026 年中国节假日判断峰谷；未知模型或其他日历年份仅记录用量。价表随插件版本更新，并非实时拉取。

名称与分组调整会更新历史报表的展示，修改单价只影响后续调用。已有自定义配置不会被升级覆盖。重置／删除账本配置保留 DSH 模型配置与历史调用。历史及停用路由单独折叠展示；只有账本配置、没有历史和当前模型配置的路由，删除后会从列表消失。

统计边界与本地数据

• CNY/USD 是展示折算，固定使用 1 CNY = 0.14 USD，不是实时汇率，也不是供应商的币种结算比例。
• 调用结束并上报用量后计入；页面可见时每 10 秒刷新。「今日」按客户端本地日历计算。
• 金额是估算费用，不是官方账单、余额、预算或订阅扣费。部分调用未计价时，只汇总已知费用。
• 历史金额和原始单价不变。疑似将 USD 数字标成 CNY 的旧记录会显示提示，不自动重算。
• 非缓存输入与缓存 Token 分开计价，推理 Token 不重复累加；适配器需要提供兼容的标准化用量。
• 安装前的调用不补录。缺失用量无法恢复，当前进程会显示缺失次数。嵌套调用会去重，但一个外层调用扇出多个上游流仍可能漏计。
• 配置位于 $DSH_HOME/api-ledger/config.json；逐次记录保存在 records.jsonl，rollup.json 为派生汇总。未设置 DSH_HOME 时使用 ~/.dsh/api-ledger/。这些本地数据及凭据不随插件分发。内存最多保留最近 200,000 条记录。
